If your iPhone has a lightning port/requires a lightning cable to charge it, then it has a Tristar IC chip.
Apple designed the phone to require MFi (Made For iPhone) certified cables, otherwise, you can risk damaging the IC & needing a microsoldering repair.
Anker makes great MFi charging cables, which you can find here: https://amzn.to/35IzmnH
When Tristar fails, it causes your iPhone not to charge. Usually Tristar will fail after using a low quality aftermarket cable.
Tristar is an IC on the motherboard that controls the charging function.
If you take your iPhone to a repair shop, they may try replacing the charging port to solve the charging issue, but if that doesn’t solve it, then the issue is very likely Tristar.
To replace Tristar, it requires microsoldering. This is an advanced type of repair, so not every shop can do it. In fact, majority of shops cannot microsolder.
